PROXY STATEMENT AND
MANAGEMENT INFORMATION CIRCULAR

Annual Meeting of Shareholders
to be held on June 4, 2019

GENERAL PROXY INFORMATION

SOLICITATION OF PROXIES

This Proxy Statement and Management Information Circular (this “Circular”) is furnished in connection with the solicitation of proxies by the management of MDC Partners Inc. (“MDC Partners,” “MDC” or the “Company”) for use at the annual meeting of shareholders of MDC Partners to be held at the time and place and for the purposes set forth in the accompanying Notice of Annual Meeting of Shareholders, and any adjournments or postponements thereof. Such meeting is hereinafter referred to as the “Meeting”.

The Meeting constitutes the Company’s annual meeting of shareholders. The information contained in this Circular is given as of the date hereof, except as otherwise noted herein. The address of the principal executive office of MDC Partners is 745 Fifth Avenue, 19th Floor, New York, NY 10151, and its registered address is 33 Draper Street, Toronto, Ontario M5V 2M3. This Circular, the accompanying notice and the enclosed form of proxy are expected to first be mailed to shareholders on or about Thursday, April 30, 2019.

Management expects that proxies will be solicited primarily by mail. While it is expected that the solicitation will be made primarily by mail, proxies may be solicited personally or by telephone. Employees who help us in the solicitation will not be specially compensated for those services but they may be reimbursed for their out-of-pocket expenses incurred in connection with the solicitation. If a holder holds his, her or its shares in the name of a bank, broker or other nominee, see “Beneficial Owners” below.

MANNER IN WHICH PROXIES WILL BE VOTED

The shares represented by the accompanying form of proxy, if the same is properly executed in favor of Messrs. Penn and Gendel, the management nominees, and received at the offices of AST Trust Company (Canada), Attn: Proxy Department, P.O. Box 721, Agincourt, Ontario M1S 0A1 (the “Transfer Agent”) not later than 10:00 a.m. (Eastern Daylight Time) on Friday, May 31, 2019 (or, if the Meeting is adjourned or postponed, not later than 48 hours, excluding Saturdays, Sundays and holidays, preceding the time of such adjourned or postponed Meeting), will be voted or withheld from voting at the Meeting and, where a choice is specified in respect of any matter to be acted upon, will be voted in accordance with the specifications made. The proxy cut off time may be waived or extended by the Chairman of the Meeting without notice. In the absence of such a specification, to the extent permitted, such shares will be voted (i) FOR the election of each of the eight (8) nominees for the Board of Directors of MDC Partners named in this Proxy Statement; (ii) FOR the appointment of BDO USA, LLP as auditors of MDC Partners and to authorize the Audit Committee to fix their remuneration; and (iii) FOR the approval, on an advisory basis, of the compensation of the Company’s named executive officers. The accompanying form of proxy confers discretionary authority upon the persons named therein with respect to amendments or variations to matters identified in the accompanying Notice of Annual Meeting of Shareholders, and with respect to other matters which may properly come before the Meeting. At the date hereof, management knows of no such amendments, variations or other matters.

At any meeting of shareholders (including the 2019 Annual Meeting of Shareholders), a quorum for the transaction of business will be not less than 33 1/3% of the shares entitled to vote at the meeting, represented either in person or by proxy. Only a shareholder of record at the close of business on April 12, 2019 (the “record date”) will be entitled to vote, or grant proxies to vote, his or her Class A Subordinate Voting Shares (“Class A Shares”) or Class B Shares (“Class B Shares”) (the Class A Shares and the Class B Shares are herein referred to collectively as the “shares”) at the Meeting (subject, in the case of voting by proxy, to the timely deposit of his or her executed form of proxy as described herein).

3

All matters are ordinary resolutions which must be passed by at least a majority of the votes cast by shareholders present in person or represented by proxy who voted in respect of the ordinary resolution at the Meeting, except for the election of directors, who are elected by a plurality of the votes cast. Broker non-votes and abstentions are included in the calculation of the number of votes considered to be present at the Meeting for purposes of determining a quorum, but otherwise will not affect the voting outcome of the proposals. An automated system administered by the Transfer Agent tabulates the votes.

ALTERNATE PROXY

Each shareholder has the right to appoint a person other than the persons named in the accompanying form of proxy, who need not be a shareholder, to attend and act for him or her and on his or her behalf at the Meeting. Any shareholder wishing to exercise such right may do so by inserting in the blank space provided in the accompanying form of proxy the name of the person whom such shareholder wishes to appoint as proxy and by duly depositing such proxy, or by duly completing and depositing another proper form of proxy and depositing the same with the Transfer Agent at the address and within the time specified under “Manner In Which Proxies Will Be Voted” above. If you are appointing a non-management proxyholder please ensure they attend the Meeting for your vote to count.

REVOCABILITY OF PROXY

A shareholder giving a proxy has the power to revoke it. Such revocation may be made by the shareholder by duly executing another form of proxy bearing a later date and duly depositing the same before the specified time, or may be made by written instrument revoking such proxy executed by the shareholder or by his or her attorney authorized in writing or, if the shareholder is a body corporate, by an officer or attorney thereof duly authorized, and deposited either at the corporate office of MDC Partners, 745 Fifth Avenue, 19th Floor, New York, NY 10151, not later than 10:00 a.m. (Eastern Daylight Time) on Friday, May 31, 2019 (or, if the Meeting is adjourned or postponed, not later than 48 hours, excluding Saturdays, Sundays and holidays, preceding the time of such adjourned or postponed Meeting), or with the Chairman of the Meeting on the day of the Meeting or any adjournment or postponement thereof. If such written instrument is deposited with the Chairman of the Meeting on the day of the Meeting or any adjournment or postponement thereof, such instrument will not be effective with respect to any matter on which a vote has already been cast pursuant to such proxy.

BENEFICIAL OWNERS

Most shareholders are “beneficial owners” who are non-registered shareholders. Their shares are registered in the name of an intermediary, such as a securities broker, financial institution, trustee, custodian or other nominee who holds the shares on their behalf, or in the name of a clearing agency in which the intermediary is a participant (such as The Canadian Depository for Securities Limited). Intermediaries have obligations to forward meeting materials to the non-registered holders, unless otherwise instructed by the holder (and as required by regulation in some cases, despite such instructions).

Only registered shareholders or their duly appointed proxyholders are permitted to vote at the Meeting. Non-registered holders should follow the directions of their intermediaries with respect to the procedures to be followed for voting. Generally, intermediaries will provide non-registered holders with either: (a) a voting instruction form for completion and execution by the non-registered holder, or (b) a proxy form, executed by the intermediary and restricted to the number of shares owned by the non-registered holder, but otherwise uncompleted. These are procedures to permit the non-registered holders to direct the voting of the shares that they beneficially own.

If the non-registered holder wishes to attend and vote in person at the meeting, they must insert their own name in the space provided for the appointment of a proxyholder on the voting instruction form or proxy form provided by the intermediary, and carefully follow the intermediary’s instructions for return of the executed form or other method of response.

If the non-registered shareholder does not provide voting instructions to its intermediary, the shares will not be voted on any proposal on which the intermediary does not have discretionary authority to vote. Under current rules, certain intermediaries will not have discretionary authority to vote shares at the

4

Meeting on any of the proposals. We encourage all non-registered shareholders to provide instructions to the securities broker, financial institution, trustee, custodian or other nominee who holds the shares on their behalf by carefully following the instructions provided.

CURRENCY

The current liquidation preference of each Series 4 Preference Share is $1,178, subject to an 8% accretion, compounded quarterly until March 7, 2022. The current Series 4 Conversion Price is $7.42 per Series 4 Preference Share, subject to customary anti-dilution protection. The Series 4 Preference Shares are also convertible at the Company’s option (i) on and after March 7, 2019, if the closing trading price of the Class A Shares over a specified period prior to conversion is at least 125% of the then-applicable Series 4 Conversion Price or (ii) after March 7, 2022, if the closing trading price of the Class A Shares over a specified period prior to conversion is at least equal to the then-applicable Series 4 Conversion Price.

The Series 6 Preference Shares do not entitle their holders to vote in the election of directors and, other than as required by applicable law, holders of the Series 6 Preference Shares will not have voting rights. The holders of the Series 6 Preference Shares have the right to convert the Series 6 Preference Shares at any time and from time to time into a number of Class A Shares equal to the then-applicable liquidation preference divided by the applicable conversion price at such time (the “Series 6 Conversion Price”). The initial liquidation preference of each Series 6 Preference Share is $1,000, subject to an 8% accretion, compounded quarterly until March 14, 2024. The initial Series 6 Conversion Price is $5.00 per Series 6 Preference Share, subject to customary anti-dilution protection. The Series 6 Preference Shares are also convertible at the Company’s option (i) on and after March 14, 2021, if the closing trading price of the Class A Shares over a specified period prior to conversion is at least 125% of the then-applicable Series 6 Conversion Price or (ii) after March 14, 2024, if the closing trading price of the Class A Shares over a specified period prior to conversion is at least equal to the then-applicable Series 6 Conversion Price.

The holders of the Class A Shares are entitled to one vote in respect of each Class A Share held in connection with each matter to be acted upon at the Meeting, the holders of the Class B Shares are entitled to twenty votes in respect of each Class B Share held in connection with each matter to be acted upon at the Meeting; the holders of the Series 4 Preference Shares and Series 6 Preference Shares are not entitled to

5

vote in connection with the matters to be acted upon at the Meeting. Approximately 99.9% of the aggregate voting rights attached to the issued and outstanding shares of MDC Partners are represented by the Class A Shares. Cumulative voting in the election of directors is not permitted.

The articles of MDC Partners contain provisions providing that, in the event an offer is made to purchase Class B Shares which must, by reason of applicable securities legislation or the requirements of a stock exchange on which the Class B Shares are listed, be made to all or substantially all of the Class B Shares, and which offer is not made on identical terms, as to price per share and percentage of outstanding shares, to purchase the Class A Shares, the holders of Class A Shares shall have the right to convert such shares into Class B Shares in certain specified instances.

To the knowledge of the directors and officers of MDC Partners, and excluding the Series 4 and Series 6 Preference Shares, no person (or group of persons) beneficially owns, directly or indirectly, or exercises control or direction over, voting securities of MDC Partners representing more than 5% of the voting rights attached to any class of voting securities of MDC Partners other than: Stagwell Agency Holdings LLC, Indaba Capital Management, L.P. and Hotchkis and Wiley Capital Management LLC. See “Security Ownership of Management and Certain Beneficial Owners” for details of shares beneficially owned by these persons and entities.

EXPENSES

MDC Partners will pay all of the expenses of soliciting proxies for management. In addition to the mailing of the proxy material, such solicitation may be made in person or by telephone by directors, officers and employees of MDC Partners, whose directors, officers and employees will receive no compensation for such solicitation other than their regular salaries or fees.

PARTICULARS OF MATTERS TO BE ACTED UPON

ITEM 1 — ELECTION OF DIRECTORS

The Requisition included an item of business consisting of a resolution setting the number of directors of MDC Partners at eight (8). The Board has independently determined that eight (8) directors will be elected at the Meeting this year based on the mix of skills and experience necessary for the Board to fulfill its duties and responsibilities. Accordingly, the business of the Meeting does not include an ordinary resolution fixing the size of the Board.

The term of office of each of the present directors expires at the Meeting. The eight (8) persons named below will be presented for election to the Board of Directors at the Meeting as management’s nominees, and, unless otherwise instructed, the persons named in the accompanying proxy (provided the same is duly executed in their favor and is duly deposited) intend to vote FOR the election of the nominees whose names are set forth below.

MDC Partners believes that each of the above nominees for election as director possess the personal and professional qualifications necessary to serve as a member of the Board, including the particular experience, talent, expertise and background set forth in “Information Concerning Management’s Nominees for Election as Directors”, below. The Board therefore unanimously recommends a vote “For” the election of its nominees.

Each director elected will hold office until the next annual meeting of shareholders or until his or her successor is duly elected or appointed, unless his or her office is earlier vacated in accordance with the by-laws of MDC Partners. Management does not contemplate that any of its nominees will be unable to serve as a director but, if that should occur for any reason prior to the Meeting, the persons named in the accompanying proxy reserve the right to vote for another nominee in their discretion.

With the exception of Mr. Penn and Mr. Gross, the Board has determined that all of the nominees are independent under applicable Nasdaq rules and the Board’s governance principles and are independent under applicable Canadian securities laws. In addition, pursuant to applicable requirements of the Canada Business Corporations Act (the “CBCA”), MDC Partners is required to have at least 25% resident Canadian directors. Ms. O’Donovan and Mr. Goldberg are resident Canadians.

Information Concerning Management’s Nominees for Election as Directors

The following information relating to the nominees as directors, including their principal occupations and positions for the past five years and in certain cases prior years, is based partly on MDC Partners’ records and partly on information received by MDC Partners from such persons and is given as of April 30, 2019:

Mark J. Penn, age 65, has been the Chief Executive Officer of MDC Partners since March 18, 2019 and the Chairman of the Board since April 18, 2019. He has also been the President and Managing Partner of The Stagwell Group, a private equity fund that invests in digital marketing services companies, since its formation in June 2015. Prior to The Stagwell Group, Mr. Penn served in various senior executive positions at Microsoft. As Executive Vice President and Chief Strategy Officer of Microsoft, he was responsible for working on core strategic issues across the company, blending data analytics with creativity. Mr. Penn also has extensive experience growing and managing agencies. As the co-founder and CEO of Penn Schoen Berland, a market research firm that he built and later sold to WPP Group, he demonstrated value-creation, serving clients with innovative techniques such as being the first to offer overnight polling and unique ad testing methods now used by politicians and major corporations. At WPP Group, he also became CEO of Burson-Marsteller, and managed the two companies to substantial profit growth during that period. A globally recognized strategist, Mr. Penn has advised corporate and political leaders both in the United

8

States and internationally.

Internationally, Mr. Penn helped elect more than 25 leaders in Asia, Latin America and Europe, including Tony Blair and Menachem Begin.

He has also been a columnist for the Wall Street Journal, Time.com, POLITICO, The Hill, and the Huffington Post, and is a visiting lecturer at Harvard College where he teaches courses on Public Opinion. Mr. Penn has extensive leadership experience as an agency operator, and his background as an agency founder, executive strategist and marketer, and global thought leader were critical qualifications that led to his appointment as CEO and a member of the Board. Mr. Penn resides in Washington, D.C. Mr. Penn was nominated by Stagwell Agency Holdings LLC pursuant to its rights as purchaser of the Class A Subordinate Voting Shares and Series 6 Convertible Preference Shares.

Information about the Board and Corporate Governance

The Board oversees the management of the business and affairs of MDC Partners as required by Canadian law. The Board conducts its business through meetings of the Board and three standing committees: the Audit Committee, the Human Resources & Compensation Committee and the Nominating and Corporate Governance Committee.

The Board has established guidelines for determining director independence, and all current directors, with the exception of Mr. Penn, Mr. Kauffman and Mr. Gross, have been determined by the Board to be independent under applicable Nasdaq rules and the Board’s governance principles, and applicable Canadian securities laws within the meaning of National Instrument 58-101 — Disclosure of Corporate Governance Practices.

MDC Partners has also adopted a written Code of Conduct in order to help directors, officers and employees resolve ethical issues in an increasingly complex business environment. The Code of Conduct applies to all directors, officers and employees, including the Chief Executive Officer, the Chief Financial Officer, the General Counsel and any other employee with any responsibility for the preparation and filing of documents with the Securities and Exchange Commission (“SEC”). The Code of Conduct covers topics including, but not limited to, conflicts of interest, confidentiality of information and compliance with laws. The Code of Conduct also satisfies the requirements for a code of ethics, as defined by Item 406 of Regulation S-K promulgated by the SEC. In addition, the Board of MDC Partners adopted a set of Corporate Governance Guidelines as a framework within which the Board and its committees conduct business.

The Company’s Corporate Governance Guidelines contain a majority voting policy, which requires a director nominee who receives, in an uncontested election, a number of votes “withheld” that is greater than the number of votes cast “for” his or her election to promptly offer to resign from the Board. The Board shall accept the resignation absent exceptional circumstances. Unless the Board decides to reject the offer, the resignation shall become effective 60 days after the date of the election. In making a determination whether to reject the offer or postpone the effective date, the Board of Directors shall consider all factors it considers relevant to the best interests of the Company. A director who tenders a resignation pursuant to the Corporate Governance Guidelines will not participate in any meeting of the Board at which the resignation is considered. The Company will promptly issue a news release with the Board’s decision.

Copies of the charters of the Audit Committee, the Human Resources & Compensation Committee and the Nominating and Corporate Governance Committee, as well the Code of Conduct and Corporate Governance Guidelines, are available free of charge at MDC Partners’ website located at http://www.mdc-partners.com/investors/corporate-governance. Copies are also available to any shareholder upon written request to 745 Fifth Avenue, 19th Floor, New York, NY 10151, Attn: Investor Relations.

Meetings

The Board held fifteen (15) meetings in 2018. All current members of the Board who served as directors during 2018 attended each Board meeting during the period in which they served in 2018.

The various Board committees met the number of times shown in parentheses: Audit Committee (5); Human Resources & Compensation Committee (6); and Nominating & Corporate Governance Committee (1). Each incumbent director that served as a director during 2018 attended all meetings of all Board committees on which they served during such period. MDC has a formal policy regarding attendance by

16

directors at its annual general meetings of shareholders which states that all directors are expected to attend, provided that a director who is unable to attend such a meeting is expected to notify the Chairman of the Board in advance of any such meeting. Each member of the Board who served as a director during 2018 attended the 2018 annual meeting of shareholders, other than Mr. Copeland.

Committees of the Board

The Board currently has three standing committees: the Audit Committee, the Human Resources & Compensation Committee and the Nominating & Corporate Governance Committee. In October 2018, the Board also formed the Strategic Alternatives Review Committee, composed of Irwin Simon, Larry Kramer and Anne Marie O’Donovan, for the purpose of overseeing the review of strategic alternatives and the appointment of a successor Chief Executive Officer. The Board’s evaluation of strategic alternatives is now complete following the $100 million investment made by Stagwell and the appointment of Mark Penn as the Company’s new Chief Executive Officer, effective March 18, 2019. Accordingly, the Strategic Alternatives Review Committee is no longer active. The terms of reference and mandate for each committee of the Board are summarized below.

Membership on Standing Board Committees

Audit Committee

The Audit Committee is currently composed of four (4) members, all of whom are considered to be “independent” according to the applicable rules of Nasdaq, the Securities and Exchange Commission and applicable Canadian laws. The Audit Committee reviews all financial statements, annual and interim, intended for circulation to shareholders and reports upon these to the Board. In addition, the Board may refer to the Audit Committee on matters and questions relating to the financial position of MDC Partners and its affiliates. The Audit Committee is also responsible for overseeing and reviewing with management and the independent auditor the adequacy and effectiveness of the Company’s accounting and internal control policies and procedures; risk oversight matters; reviewing with management its compliance with prescribed policies, procedures and internal controls; and reviewing with management and the independent auditor their reports on internal controls, as presented in Item 9A (Controls and Procedures) of the Company’s Annual Report on Form 10-K for the year ended December 31, 2018. While the Audit Committee has the duties and responsibilities set forth above, the Audit Committee is not responsible for planning or conducting the audit or for determining whether the Company’s financial statements are complete and accurate and are in accordance with generally accepted accounting principles. Management has the responsibility for preparing the financial statements and implementing internal controls and evaluating their effectiveness, and the independent auditor has the responsibility of auditing the financial statements and effectiveness of internal controls over financial reporting.

The current members of the Audit Committee are: Anne Marie O’Donovan (Chairperson), Charlene Barshefsky, Daniel Goldberg and Larry Kramer. The Board has determined that Ms. O’Donovan qualifies

17

as an “audit committee financial expert” under the Sarbanes-Oxley Act of 2002 and applicable Nasdaq and Securities and Exchange Commission regulations. In addition, each of the members of the Audit Committee is “financially literate” as required by applicable Canadian securities laws. The Audit Committee’s current charter is appended hereto as Exhibit A and is available at http://www.mdc-partners.com/investors/corporate-governance. The Company will disclose any amendments to, or waivers of, the charter on its website at www.mdc-partners.com in accordance with applicable law and the requirements of the Nasdaq corporate governance standards.

Nominating & Corporate Governance Committee

The Nominating & Corporate Governance Committee is composed of five (5) members, all of whom are considered to be “independent” according to the applicable rules of Nasdaq and the Securities and Exchange Commission and by applicable Canadian securities laws. The Nominating & Corporate Governance Committee is responsible for reviewing and making recommendations to the full Board with respect to developments in the area of corporate governance and the practices of the Board. The Nominating & Corporate Governance Committee is also responsible for evaluating the performance of the Board as a whole and for reporting to the Board with respect to appropriate candidates for nominations to the Board. The current members of the Nominating & Corporate Governance Committee are: Irwin Simon (Chairman), Charlene Barshefsky, Daniel Goldberg, Anne Marie O’Donovan and Desirée Rogers. The Nominating & Corporate Governance Committee’s current charter is available at http://www.mdc-partners.com/investors/corporate-governance. The Company will disclose any amendments to, or waivers of, the charter on its website at www.mdc-partners.com in accordance with applicable law and the requirements of the Nasdaq corporate governance standards.

Human Resources & Compensation Committee

The Human Resources & Compensation Committee (the “Compensation Committee”) is currently composed of four (4) members. The current member are Larry Kramer (Chairman), Clare Copeland, Desirée Rogers and Irwin Simon. All of the members of the Compensation Committee are considered to be “independent” according to the applicable rules of Nasdaq and the Securities and Exchange Commission and applicable Canadian securities laws, and outside directors within the meaning of Section 162(m) of the Internal Revenue Code of 1986, as amended (the “Code”), and non-employee directors within the meaning of Rule 16b-3 under the Exchange Act. The Compensation Committee makes recommendations to the Board on, among other things, the compensation of senior executives. The Compensation Committee discusses personnel and human resources matters including recruitment and development, management succession and benefits plans and grants awards under the SARs Plan, the 2016 Stock Incentive Plan and the 2008 Key Partners Incentive Plan (each as defined below). Salary, bonus or other payments for the benefit of senior management are reviewed and approved by the Compensation Committee. From 2016 through 2018, the Compensation Committee engaged Mercer Human Resource Consulting LLC to review and evaluate the Company’s executive compensation levels, and to make recommendations for compensation of the Company’s executive officers based on comparable industry levels, which recommendations have been implemented by the Compensation Committee. The Compensation Committee’s current charter is available at http://www.mdc-partners.com/investors/corporate-governance. The Company will disclose any amendments to the charter on its website at www.mdc-partners.com in accordance with applicable law and the requirements of the Nasdaq corporate governance standards.

Board Leadership, Executive Sessions and Communications with the Board

Presently, Mr. Penn is the Chairman of the Board. The Board does not require the separation of the offices of Chairman of the Board and Chief Executive Officer. All of the Company’s directors, whether members of management or not, have a fiduciary duty to exercise their business judgment in the best interests of the Company. The Board believes separating the roles of Chairman of the Board and Chief Executive Officer would not diminish or augment these fiduciary duties. The Board deliberates and decides, each time it selects a Chairman of the Board, whether the roles should be combined or separate, based upon the then current needs of the Company and the Board. The Board believes that the Company is currently best served by having Mr. Penn hold the positions of both Chairman and Chief Executive Officer,

18

and by having a separate independent director (currently Mr. Simon) serve as “Presiding Director.” In the Board’s view, the current leadership structure facilitates strong communication and coordination between management and the Board and enables the Board to adeptly fulfill its risk oversight responsibilities.

Non-employee directors frequently meet in executive sessions without management in conjunction with each regularly scheduled Board meeting. The Company’s Presiding Director has the primary responsibility to preside over these sessions of the Board. The current Presiding Director is Irwin Simon; he was appointed to that position effective July 20, 2015. Additional information about the role of the Presiding Director is set forth in the Company’s Corporate Governance Guidelines, which are available free of charge at MDC Partners’ website at http://www.mdc-partners.com/investors/corporate-governance. Shareholders or other interested parties who wish to communicate with the Presiding Director or any other member of the Board may do so by mail or courier, to MDC Partners Inc., c/o Mitchell Gendel, EVP, General Counsel, 745 Fifth Avenue, 19th Floor, New York, NY 10151. To facilitate a response, in appropriate circumstances, shareholders are asked to provide the following information: (i) their name; (ii) an address, telephone number, fax number and e-mail address at which they can be reached; and (iii) the number of shares or aggregate principal amount of debt that they hold, and the date those securities were acquired.

The Board has extensive involvement in the oversight of risk management related to us and our business. The Board accomplishes this oversight both directly and through its committees, each of which assists the Board in overseeing a part of our overall risk management and regularly reports to the Board. The Audit Committee represents the Board by periodically reviewing our accounting, reporting and financial practices, including the integrity of our financial statements, the surveillance of administrative and financial controls and our compliance with legal and regulatory requirements. Through its regular meetings with management, including the finance, legal and compliance and risk management functions, the Audit Committee reviews and discusses all significant areas of our business and summarizes for the Board all areas of risk and the appropriate mitigating factors. The Human Resources & Compensation Committee considers, and discusses with management, management’s assessment of certain risks, including whether any risks arising from our compensation policies and practices for our employees are reasonably likely to have a material adverse effect on us. The Nominating & Corporate Governance Committee oversees and evaluates programs and risks associated with Board organization, membership and structure and corporate governance. In addition, our Board receives periodic detailed operating performance reviews from management.

With respect to cybersecurity risk oversight, our Board of Directors and our Audit Committee receive periodic reports from the appropriate managers on the primary cybersecurity risks facing the Company and the measures the Company is taking to mitigate such risks. In addition to these periodic reports, our Board of Directors and our Audit Committee receive updates from management as to changes to the Company’s cybersecurity risk profile or significant newly identified risks.

Director Nominations

The Nominating and Corporate Governance Committee identifies, selects and recommends to the Board individuals qualified to serve both on the Board and committees, including persons suggested by shareholders and others. While the Board has not adopted a formal policy for diversity in identifying director nominees, the Nominating and Corporate Governance Committee seeks to maintain at all times a Board with a diverse range of experience, talent, expertise and background appropriate for the business of the Company. In April 2018, the Company’s internal recruiting department identified an extensive list of potential candidates to join the Board. From that list of potential candidates, the Nominating and Corporate Governance Committee determined to nominate Desirée Rogers, who was subsequently appointed to the Board on April 26, 2018. Each of Mr. Penn and Ambassador Barshefsky was nominated by Stagwell pursuant to its rights in connection with the purchase of both Class A Subordinate Voting Shares and Series 6 Preference Share. Ms. O’Hara was nominated pursuant a settlement agreement, dated April 19, 2019, by and between MDC and FrontFour Capital Group LLC.

The Nominating and Corporate Governance Committee does not require any specific minimum qualifications or specific qualities or skills, but reviews each person’s qualifications on the whole, including a candidate’s particular experience, skills, expertise, diversity, personal and professional integrity, character, business judgment, time availability in light of other commitments, dedication, conflicts of interest and

19

such other relevant factors that the Nominating and Corporate Governance Committee considers appropriate in the context of the needs of the Board. Following that review, the Nominating and Corporate Governance Committee then selects nominees and recommends them to the Board for election by the shareholders or appointment by the Board, as the case may be. The Nominating and Corporate Governance Committee also reviews the suitability of each Board member for continued service as a director when that member’s term expires or that member experiences a significant change in status (for example, a change in employment). The Nominating and Corporate Governance Committee has not implemented any particular additional policies or procedures with respect to suggestions received from shareholders with respect to Board or committee nominees.

Pursuant to its charter, the Nominating and Corporate Governance Committee may conduct or authorize investigations or studies into matters within its scope of responsibilities and may retain, at the Company’s expense, such independent counsel or other consultants or advisers as it may deem necessary from time to time. The Nominating and Corporate Governance Committee has the sole authority to retain or terminate any search firm to be used to identify director candidates, including the sole authority to approve its fees and terms, with the Company bearing the cost of such fees. The Nominating and Corporate Governance Committee will formally meet and deliberate on the qualifications of specific candidates prior recommending their appointment to the full Board. The Nominating and Corporate Governance Committee utilizes the same criteria for evaluating candidates regardless of the source of the referral.

Compensation of Directors

MDC pays certain directors who are not employees of MDC or any of its subsidiaries a $70,000 annual retainer. MDC also pays a fee of  $2,000 for attendance at any Board or Committee meeting. Fees for director attendance at meetings are limited to two meetings per day. MDC pays an additional retainer for certain positions held by a director: $75,000 for the Presiding Director, $20,000 for the Audit Committee Chair, $5,000 for the Audit Committee financial expert and $15,000 for other Committee Chairs. In addition, certain non-employee directors are eligible to receive an annual grant of restricted stock with a grant date market value of approximately $100,000, typically vesting on the third anniversary of the grant date.

In 2018, Mr. Kauffman was not entitled to receive any separate or additional compensation in connection with his services on the Board. Mr. Gross, the nominee director of Goldman Sachs, and Mr. Penn, the nominee director of Stagwell, also do not receive any compensation for their services on the Board.

The following table sets forth the compensation paid to or earned during fiscal year 2018 by our non-management directors:

COMPENSATION DISCUSSION AND ANALYSIS

This Compensation Discussion and Analysis (or “CD&A”) section outlines our compensation philosophy and describes the material components of our executive compensation practices for Mr. Penn (our current CEO, who was appointed effective on March 18, 2019), Mr. Kauffman (our former CEO), David Doft (our CFO) and our other named executive officers (or “NEOs”).

EXECUTIVE SUMMARY

In 2018, the Compensation Committee reaffirmed its commitment to adhere to our “pay-for-performance” requirements with respect to all new incentive awards granted to the CEO and NEOs.

Continued Improvements to Governance and Compensation Practices in Response to Shareholder Feedback:

Our annual “Say-on-Pay” advisory vote in 2018 continued to improve substantially, as approximately 94% of votes cast were voted in favor of our executive compensation program, as compared to only 53% in respect of 2015.

In response to the disappointing 2015 voting results, management and the Board undertook a concentrated effort to focus on shareholder outreach and solicitation of feedback in subsequent years. Based on shareholder feedback, and as part of the Company’s continuous efforts to implement executive compensation programs that align the interests of management with our shareholders, the Board adopted and has continued to implement several governance and compensation-related changes.

In addition, MDC’s Board and management team implemented several governance and compensation-related remedial measures focused on improved internal controls and corporate governance initiatives. Each of the remedial measures and improved compensation practices summarized below, were consistent with the changes suggested by our largest shareholders. Importantly, in January 2017, we announced that we fully settled the SEC investigation with no finding by the SEC of intentional wrongdoing by any current directors or officers. In addition, we prevailed in having each of the U.S. and Canadian securities class action litigation claims dismissed, with prejudice (each as described in greater detail in our Annual Report on Form 10-K for the year ended December 31, 2018).

Implementation of  “Pay for Performance” Measures; Failure to Achieve 2018 Performance Metrics.   For 2018 annual incentive awards, the Compensation Committee reaffirmed its commitment to using “pay-for-performance” incentive arrangements based solely on the achievement of financial targets and individual performance criteria. The Company failed to achieve the 2018 financial targets established by the Compensation Committee. Accordingly, the Compensation Committee determined not to authorize cash payments to the former CEO and each other NEO in respect of their 2018 financial performance-based cash incentives.

​

•

Grants of Restricted Stock Awards with Vesting Based Solely on Financial Performance; Forfeiture of 2016 Restricted Stock/ RSU Awards.   All grants of restricted stock to executive officers in 2016, 2017 and 2018 contain financial performance-based vesting requirements; they are not just subject to time-based vesting requirements. The Company failed to achieve the three-year financial performance targets for 2016-2018 in connection with equity incentive awards granted in 2016 (the “2016 RSU Awards”). Accordingly, the 2016 RSU Awards to the former CEO and each NEO were forfeited and cancelled, effective in March 2019.

​

•

New CEO Compensation Terms Fully Aligned with Financial Performance and Equity Appreciation.   Effective March 18, 2019, following an extensive search process, the Company appointed Mark Penn as its new Chief Executive Officer. The compensation terms for Mr. Penn were determined based on feedback from the Committee’s advisors (Mercer Human Resource Consulting LLC, “Mercer”) and were benchmarked against appropriate comparator companies. Importantly, Mr. Penn’s incentive compensation for 2019 and subsequent years is heavily dependent upon achievement of the Company’s financial performance targets, and the ultimate value of his initial inducement award of SARS will be directly based upon appreciation of the price of the Company’s Class A shares.

​

22

•

Greater Majority of Board of Directors Currently Independent.   Several institutional shareholders suggested that a greater percentage of the Company’s Board of Directors should be independent. As part of the Board’s commitment to stronger corporate governance initiatives, the Board is currently composed of nine (9) non-management directors and one (1) management director. Accordingly, 90% of the current Board of Directors is comprised of non-management directors, as compared to April 2015.

​

We firmly believe that the implementation of the foregoing improvements to our governance and compensation practices described above has appropriately addressed all of our key shareholders’ concerns.

OVERVIEW OF OUR COMPENSATION PROGRAM FOR NAMED EXECUTIVE OFFICERS

The Company traditionally uses a mix of short- and long-term and fixed and variable elements in compensating the NEOs: base salary; annual cash bonus incentives; and long-term incentive awards. In prior years, long-term incentive awards often included equity-based awards that vested based solely on continued employment. However, as described in more detail below, the Compensation Committee redesigned the long-term incentive program for our NEOs so that all future long-term equity awards granted to NEOs will either be subject to performance-based vesting requirements or will have value only to the extent that our stock price increases following the grant date.

Compensation Philosophy

In 2018, the Compensation Committee reaffirmed its compensation strategy to appropriately link compensation levels with shareholder value creation by:

•

Aligning pay with financial performance as a meaningful component of total compensation;

​

•

Providing total compensation capable of attracting, motivating and retaining executives of outstanding talent;

​

•

Focusing our executives on achieving key objectives critical to implementing the Company’s business strategy and achieving financial performance goals;

​

•

Imposing and enforcing appropriate “claw-back” repayment requirements for resignation or termination for cause; and

​

•

Safeguarding the Company’s business interests, including protection from adverse activities by executives.

​

Risk Assessment

The Compensation Committee reviews with management the design and operation of the Company’s performance goals and metrics used in connection with incentive awards and determined that these policies do not provide the Company’s executive officers or other employees with incentive to engage in behavior that are reasonably likely to have a material adverse effect on the Company. As discussed below in greater detail, the principal measures of our business performance to which named executive officer compensation is tied are Adjusted EBITDA (as defined below) and individual key performance criteria, and in the case of equity incentive awards, the value returned to shareholders as measured by stock price appreciation, as compared to a specified peer group of companies.

Process for Determining the Compensation of our Named Executive Officers

Our Compensation Committee.   During 2018, the Compensation Committee was composed of four independent, non-employee directors. The Compensation Committee oversees the Company’s executive compensation and benefit plans and practices, including its incentive compensation and equity-based plans, and reviews and approves the Company’s management succession plans. Specifically, the Compensation Committee determines the salaries and the performance measures and awards under the annual bonus incentive program for the Chief Executive Officer and other executive officers. The Compensation

23

Committee also determines the amount and form of long-term incentive awards, which typically take the form of equity incentive grants, including shares of restricted stock under the 2016 Stock Incentive Plan, and stock appreciation rights (SARs) under the SARs Plan.

Engagement of Compensation Consultant.   In 2016, 2017 and 2018, the Compensation Committee retained Mercer, a compensation consulting firm, to provide objective analysis, advice and information to the Compensation Committee, including competitive market data and recommendations related to CEO and other executive officer compensation. Mercer reports to the Compensation Committee Chairman and has direct access to Compensation Committee members. In addition to the advice described above, the Compensation Committee engaged Mercer to assist in designing the existing LTIP Plan to enhance pay-for-performance alignment and in structuring the 2018 EVP awards. In accordance with Nasdaq listing standards and SEC regulations, the Compensation Committee assessed the independence of Mercer and determined that it was independent from management and that Mercer’s work has not raised any conflict of interest.

Mercer has attended Compensation Committee meetings at the Compensation Committee’s request and has also met with the Compensation Committee in executive session without management present. In particular, the Compensation Committee worked with Mercer to structure performance-based annual and long-term incentive programs designed to retain the Company’s executive management team and to motivate them to achieve goals that increase shareholder value. The Compensation Committee sought to ensure that its incentive plans properly align management incentive compensation targets with the performance targets most relevant to shareholders. The Compensation Committee also considered recent trends in executive compensation.

The aggregate amount of fees billed by Mercer for services related to designing the LTIP awards and determining compensation for the Company’s named executive officers was equal to approximately $9,000 for 2018.

Role of Named Executive Officers in Compensation Decisions: Input from Senior Management.   The Compensation Committee considers input from senior management in making determinations regarding the overall executive compensation program and the individual compensation of the named executive officers. As part of the Company’s annual planning process, the CEO and CFO develop targets for the Company’s incentive compensation programs and present them to the Compensation Committee. These targets are reviewed by the Compensation Committee to ensure alignment with the Company’s strategic and annual operating plans, taking into account the targeted year-over-year improvement as well as identified opportunities and risks. Based on performance appraisals, including an assessment of the achievement of pre-established financial and individual “key performance indicators,” the CEO recommends to the Compensation Committee cash and long-term incentive award levels for the Company’s other executive officers. Each year, the CEO presents to the Compensation Committee his evaluation of each executive officer’s contribution and performance over the past year, and strengths and development needs and actions for each of the executive officers. The Compensation Committee exercises its discretionary authority and makes the final decisions regarding the form of awards, targets, award opportunities and payout value of awards. No executive officer participates in discussions relating to his or her own compensation.

ELEMENTS OF OUR COMPENSATION PROGRAM FOR OUR NAMED EXECUTIVE OFFICERS

The following table details the elements of our compensation program which are designed to achieve our compensation objectives for the named executive officers:

25

In setting policies and administering the compensation of named executive officers, the Compensation Committee reviews all elements of total compensation, benefits and perquisites. The Compensation Committee reviews reports and analyses of executive compensation in consultation with its outside consultant, including current practices and trends among peer companies and the advertising and marketing services industry.

2018 Base Salaries.   The Compensation Committee reviews base salaries annually or at other times when appropriate. In determining the amount of base salary that each NEO receives, the Compensation Committee reviews the executive’s current compensation, time in position, any change in the executive’s position or responsibilities and the relation of the executive’s position and compensation to those of other executives within the Company and in similar positions at peer companies. Effective March 1, 2018, the Committee determined to increase Mr. Gendel’s annual base salary to $650,000 per year based upon his expanded scope of responsibilities with real estate, human resources and procurement matters.

2018 INCENTIVE AWARDS: FINANCIAL AND INDIVIDUAL PERFORMANCE METRICS

Pay-for-Performance Analysis; Failure to Achieve 2018 Financial Targets.   The Company’s compensation program is designed to reward performance relative to corporate financial performance criteria and individual incentive criteria. Specifically, the Company’s senior executives are eligible to receive an annual bonus each year in a target amount equal to their base salary if the Company achieves the financial performance targets established by the Compensation Committee and the CEO and each NEO is determined to have satisfied his or her individual performance criteria. The Company does not apply a formula or use a pre-determined weighting when comparing overall performance against the various individual objectives, and no single objective is material in determining individual awards.

The Company’s overall financial performance for 2018 failed to satisfy the financial target established by the Compensation Committee of Adjusted EBITDA equal to not less than $205 million. Therefore, the Compensation Committee determined to award $0 to the former CEO and other NEOs in respect of their 2018 financial-performance based annual cash incentives. Because the Company’s overall financial performance for 2018 failed to satisfy the financial target established by the Compensation Committee, the Compensation Committee did not consider the NEOs’ performance against their individual goals.

2018 Cash LTIP Awards.   In February 2018, the Compensation Committee granted awards to our NEOs in under the Company’s 2014 Long-Term Cash Incentive Plan (the “2014 LTIP Plan”) in target amounts equal to their base salaries. These grants vest at the end of the applicable three-year measurement period (January 1, 2018 - December 31, 2020), subject to achievement of financial performance criteria and continued employment. The financial performance criteria are based on the following two specific metrics that are each given 50% weight: (i) three-year cumulative EBITDA growth as measured against the approved annual EBITDA targets for such period; and (ii) relative total shareholder return (“TSR”) based on share price appreciation and dividends as compared to a pre-defined comparator group (“Comparator Group”) over the same three-year period.

Under the 2014 LTIP Plan, “EBITDA” is defined as the Company’s consolidated earnings before interest, taxes, depreciation and amortization, plus any non-cash charges for stock-based compensation which were deducted in the calculation of EBITDA, subject to adjustments by the Compensation Committee. For 2018, the EBITDA target was equal to $205 million. A payout of 90% of the target opportunity (50%) for the EBITDA metric will be made if the Company achieves a three-year cumulative EBITDA amount equal to 90% of the three-year cumulative EBITDA target; a payout at the target opportunity (50%) for the EBITDA metric will be made if the Company achieves the three-year cumulative EBITDA target; a payout of the target opportunity (50%) for the EBITDA metric plus the applicable pro rata amount of 25% of the amount by which the three-year cumulative EBITDA amount achieved exceeds the three-year cumulative EBITDA target will be made if the Company achieves a three-year cumulative EBITDA amount in excess of the three-year cumulative EBITDA target, subject to a cap of two times the target opportunity (50%) for the EBITDA metric. For performance between the specified levels, payouts will be determined based on straight-line interpolation.

Under the 2014 LTIP Plan, total TSR is calculated as A minus B expressed as a percentage, where A is the average per-share price of the applicable company’s stock at the end of the applicable performance period, and B is the average per-share price of the applicable company’s stock at the beginning of the

26

applicable performance period. In addition, for purposes of calculations of TSR, cash dividends paid on a share of stock are deemed to be reinvested in the company’s stock on the day they are paid at the average of the high and the low per-share price on that day. A payout at 50% of the target opportunity (50%) for the TSR metric will be made if the Company’s TSR is at the 50th percentile relative to the Comparator Group; a payout at the target opportunity (50%) for the TSR metric will be made if the Company’s TSR is at the 75th percentile relative to the Comparator Group; and a payout at 200% of the target opportunity (50%) for the TSR metric will be made if the Company’s TSR is at the 90th percentile relative to the Comparator Group. For performance between the specified levels, payouts will be determined based on straight-line interpolation.

These awards also vest automatically upon a change in control of the Company, or subject to achievement of financial performance targets, on a pro rata basis upon termination of the NEO’s employment without cause. The “Comparator Group” is comprised of the following publicly-traded companies: Omnicom; Interpublic Group; IAC/InterActiveCorp; Sinclair Broadcast Group; Clear Channel; John Wiley & Sons; Scholastic Corporation; Lamar Advertising; The New York Times Company; Meredith Corporation; Morningstar; and National CineMedia Inc.

2018 LTIP Equity Incentive Awards.   In February 2018, the Compensation Committee also determined to award the former CEO and each NEO restricted stock grants under the 2016 Stock Incentive Plan. Vesting for these awards is conditioned upon achievement of three (3) year financial performance targets and continued employment pursuant to the terms of an award agreement made under the Plan (the “2018 LTIP Equity Incentive Awards”). Pursuant to the terms of the 2018 LTIP Equity Incentive Awards, the shares of restricted stock granted to our NEOs will vest based upon the Company’s level of achievement of  “Actual Cumulative EBITDA” (calculated as described below) over the performance period commencing on January 1, 2018 and ending on December 31, 2020 (the “2018-2020 Performance Period”).

For purposes of the foregoing LTIP restricted stock awards and the 2016 LTIP Equity Incentive Awards described below, “EBITDA” is defined as the Company’s consolidated earnings before interest, taxes, depreciation and amortization, plus any non-cash charges for stock-based compensation which were deducted in the calculation of EBITDA. “Actual Cumulative EBITDA” is defined as the sum of the Company’s actual annual EBITDA for the fiscal years included in the relevant performance period (the 2018-2020 Performance Period in the case of the 2018 LTIP Equity Incentive Awards), as determined by the Compensation Committee. “Cumulative EBITDA Target” is defined as the sum of the EBITDA targets as set forth in the Company’s annual budget for each of the fiscal years included in the relevant performance period, in each case as determined by the Compensation Committee at the beginning of each such fiscal year. The Compensation Committee chose EBITDA as the financial performance measure under the 2018 LTIP restricted stock awards because it is a key indicator of Company profitability.

On February 28, 2018, the Company specifically issued 2018 LTIP Equity Incentive Awards to each of the NEOs in the following target amounts: Scott Kauffman — 128,342 shares; David Doft — 53,476 shares; Mitchell Gendel — 53,746 shares; Stephanie Nerlich — 26,738 shares; and David Ross — 26,738 shares. Each of the foregoing 2018 LTIP Equity Incentive Awards will vest on March 1, 2021, based on the Company’s Actual Cumulative EBITDA as described above. For achievement of an Actual Cumulative EBITDA amount equal to or greater than 90% but less than 100% of the Cumulative EBITDA Target, 75% of each 2018 LTIP Equity Incentive Award will vest. For achievement of an Actual Cumulative EBITDA amount equal to or greater than 100% of the Cumulative EBITDA Target, 100% of each 2018 LTIP Equity Incentive Award will vest. The Compensation Committee sets the EBITDA target for each of 2018, 2019 and 2020 at the beginning of each applicable year at levels the Compensation Committee believes are challenging but reasonably achievable. Under FASB ASC Topic 718, these restricted stock awards do not yet have an established grant date or grant date fair value because the financial performance target, the Cumulative EBITDA Target, is not yet established. As there is not yet a grant date under FASB ASC Topic 718, in accordance with the SEC’s disclosure rules, amounts relating to these awards are not included in the Summary Compensation Table or the Grants of Plan-Based Awards in Fiscal Year 2018 table.

Forfeiture of 2016 LTIP Equity Incentive Awards.   On January 19, 2018, the Compensation Committee determined the EBITDA target for the 2018 fiscal year and established the Cumulative EBITDA Target of approximately $629.6 million for the performance period commencing on January 1, 2016 and ending on

27

December 31, 2018 (the “2016 LTIP Performance Period”), which was the performance period for the 2016 LTIP Equity Incentive Awards issued to the NEOs on February 17, 2016. Because the Compensation Committee established the Cumulative EBITDA Target on February 22, 2018, that date was considered the grant date under FASB ASC Topic 718. Consequently, the grant date fair value of the 2016 LTIP Equity Incentive Awards is disclosed in the “Stock Awards” column of the Summary Compensation Table and these awards are disclosed in the Grants of Plan-Based Awards in Fiscal Year 2018 table. If the Company had achieved 90% or greater but less than 100% of the Cumulative EBITDA Target for the 2016 LTIP Performance Period, 75% of each NEO’s 2016 LTIP Equity Incentive Award would have vested. If the Company had achieved 100% or greater of the Cumulative EBITDA Target for the 2016 LTIP Performance Period, 100% of each NEO’s 2016 LTIP Equity Incentive Award would have vested. The Company failed to achieve 90% or greater of the Cumulative EBITDA Target for the 2016 LTIP Performance Period. Accordingly, the 2016 LTIP Equity Incentive Awards previously issued to the former CEO and each NEO were forfeited and cancelled, effective March 13, 2019.

EVP Awards Granted in 2018.   In December 2018, the Committee approved a series of one-time retention/transaction awards (the “2018 EVP Retention Awards”) for five (5) senior executives of the Company (excluding the former CEO), including each of David Doft; Mitchell Gendel; David Ross; and Stephanie Nerlich. The amount of each 2018 EVP Retention Award was equal to the applicable NEOs respective base salary or target annual bonus award. Payment of each 2018 EVP Retention Award by the Company was conditioned on continued employment through the successful closing of a significant transaction in 2019, including either a Change of Control of the Company (as defined in the Company’s 2016 Stock Incentive Plan), or the sale of assets with aggregate proceeds to the Company from any such transaction equal to not less than $100 million (each, a “Payment Event”). The Committee will confirm if the payment conditions were satisfied for the 2018 EVP Retention Awards following the successful completion of the sale of Kingsdale and the Stagwell investment transaction at a premium valuation, among other factors, including the EVPs’ service as interim co-Chief Executive Officer following the separation of employment with Mr. Kauffman as CEO announced in September 2018.

Stock Ownership Guidelines.   The Company’s stock ownership guidelines require that each named executive officer own a significant equity stake in the Company during their employment. The Compensation Committee believes that stock ownership by senior managers strengthens their commitment to the future of the Company and further aligns their interests with those of our shareholders. The Board has adopted the following stock ownership guidelines: Chief Executive Officer and Chief Financial Officer to own stock with a value of at least four (4) times his base salary; and each other named executive officer, at least three (3) times their base salary. An executive must reach his target ownership level within four years after becoming subject to the stock ownership guidelines.

Prohibition of Pledging or Hedging of the Company’s Stock.   The Board has adopted policies to prohibit any pledge or hedging of the Company’s stock by officers and directors of the Company. Currently, no stock is pledged or hedged by any of the Company’s directors or officers.

Employment Agreements.   The Company has employment or services agreements with the CEO and all of the other named executive officers. These agreements formalize the terms of the employment relationship and assure the executive of fair treatment during employment and in the event of termination while requiring compliance with restrictive covenants. Employment agreements promote complete documentation and understanding of employment terms, including strong protections for our business.

Claw-back Agreements.   In connection with the payment of cash incentive amounts to the CEO and each of the other named executive officers in respect of 2017, the Company required that each agree in writing to repay the Company a pro rata portion of his cash incentive payment if he resigned his employment or his employment was terminated for “cause” prior to December 31, 2019. These agreements also encourage long term retention of key executives by the Company.

Business Protection Terms.   The Company’s named executive officers are subject to significant contractual restrictions intended to prevent actions that potentially could harm our business, particularly after termination of employment. These business protections include obligations not to solicit clients or employees, not to disparage us, not to reveal confidential information, and to cooperate with us in litigation. Business protection provisions are included in employment agreements and in connection with compliance with the Company’s Code of Conduct.

28

Equity Award Grant Policies.   The Board of Directors and the Compensation Committee have adopted policies and procedures governing the granting of any equity incentive awards, including the following:

•

Equity incentive awards granted to executive officers must be approved by the Compensation Committee or the full Board of Directors and must be made at quarterly in-person meetings and not be made via unanimous written consent. An attorney (who may be an employee of the Company) must be present at each Compensation Committee or Board meeting.

​

•

If grants are required to be awarded in connection with hiring new employees in between quarterly Compensation Committee meetings, such grants may be approved at a special meeting, which may be telephonic or in-person.

​

•

Options, SARs and other equity incentive awards must be priced at the closing price on the date immediately prior to the date of the Compensation Committee meeting at which the grant is approved.

​

Comparator Companies.   In determining compensation opportunities and payments to executives, the Compensation Committee may, from time to time, review competitive opportunities, payments, practices and performance among a comparator group of companies. Although we do not engage in formal benchmarking of NEO compensation, we intend that, if our named executive officers achieve individual and financial corporate objectives in a given year, they will earn total direct compensation that compares favorably with the total direct compensation earned by executives performing similar functions at comparator companies. The comparator group of peer marketing service companies is comprised of the following publicly-traded companies: Omnicom; Interpublic Group; IAC/InterActiveCorp; Sinclair Broadcast Group; Clear Channel; John Wiley & Sons; Scholastic Corporation; Lamar Advertising; The New York Times Company; Meredith Corporation; Morningstar; and National CineMedia Inc.

Retirement Programs.   The Company offers each U.S.-based executive the opportunity to make individual contributions to a broad-based 401(k) Plan administered by the Company and generally available to the Company’s U.S. employees. However, the Company does not make or match any employee contributions to the 401(k) Plan for the Company’s employees. The Company does not provide any other specific retirement or pension benefits for its named executive officers.

Severance Policies.   We provide severance protection to our named executive officers in employment agreements, as detailed below under the caption “Potential Payments upon Termination or Change-In-Control.” As discussed above, this protection is designed to be fair and competitive to aid in attracting and retaining experienced executives. We believe that the protection we provide, including the level of severance payments and post-termination benefits, is appropriate. In addition, in September 2018, in connection with the resignation from his position of Chief Executive Officer of the Company, in recognition of Mr. Kauffman’s service to the Company and as inducement for Mr. Kauffman to enter into a release of claims against the Company, we entered into a succession agreement with Mr. Kauffman setting forth the terms of his separation from the Company. Mr. Kauffman’s succession agreement is also described below under the caption “Potential Payments upon Termination or Change-In-Control.”

Section 162(m).   Pursuant to Section 162(m), publicly-held corporations are prohibited from deducting compensation paid to the named executive officers as of the end of the fiscal year, in excess of $1 million, unless the compensation is “performance-based.” Although the Compensation Committee considers the impact of Section 162(m) when making its compensation determinations, the Compensation Committee has determined that its need for flexibility in designing an effective compensation plan to meet our objectives and to respond quickly to marketplace needs has outweighed its need to maximize the deductibility of its annual compensation. The Compensation Committee reviews this policy from time to time.

As used in this Proxy Statement:

“Adjusted EBITDA” is a non-U.S. GAAP measure that represents operating income (loss) plus depreciation and amortization, stock-based compensation, deferred acquisition consideration adjustments, distributions from non-consolidated affiliates, and other items, adjusted for certain items

29

at the discretion of the Compensation Committee. A reconciliation of  “Adjusted EBITDA” to the U.S. GAAP reported results of operations for the year ended December 31, 2018 is provided in the Company’s Current Report on Form 8-K filed on March 15, 2019.

COMPENSATION DECISION MADE IN 2019

Effective March 18, 2019, following an extensive search process, the Company’s Board of the Directors appointed Mark Penn as the Chief Executive Officer of the Company. The compensation terms for Mr. Penn were determined based on feedback from the Committee’s advisors (Mercer) and were benchmarked against appropriate comparator companies. Importantly, Mr. Penn’s incentive compensation for 2019 and subsequent years is heavily dependent upon achievement of the Company’s financial performance targets, and the ultimate value of his initial inducement award of SARS will be directly dependent upon appreciation of the price of the Company’s Class A shares.

More specifically, pursuant to the terms of his new employment agreement, Mr. Penn receives an annualized base salary of  $750,000 and is eligible for an annual discretionary cash bonus equal to up to 100% of his then-current base salary. He will also be eligible for potential future grants under the Company’s long-term incentive plans with an annual target equal to 350% of his then-current base salary. On April 5, 2019, Mr. Penn received a grant of 1,500,000 stock appreciation rights (the “SARs”) in respect of the Company’s Class A shares, which will generally be settled in Class A Shares, with an exercise price equal to $2.19 (the average closing price for MDC’s Class A shares for the twenty (20) trading day period beginning March 5, 2019). These SARs will become vested and exercisable in full in three equal installments on each of the first three (3) anniversaries of March 18, 2019, the “Commencement Date”, subject to Mr. Penn’s continued employment with the Company through each vesting date. The SARs will expire on the fifth anniversary of the commencement date to the extent not exercised and will be subject to accelerated vesting upon (i) death or disability, (ii) termination of employment without “Cause” or with “Good Reason,” (in each case as defined in his employment agreement) or (iii) a change in control of the Company. Mr. Penn will also receive a monthly $5,000 perquisite allowance during the term to cover automobile and travel expenses, professional dues and other perquisites.

In the event of Mr. Penn’s involuntary termination without cause or voluntary termination for “good reason”, he will be entitled to severance equal to the product of 1.5 times the sum of  (i) his then-current base salary plus (ii) the amount of his annual discretionary bonus paid in respect of the year immediately prior to the applicable date of termination, payable in a lump sum. He will also be entitled to a pro-rata portion of his annual discretionary bonus for the year of termination based on actual performance. Under the new employment agreement, Mr. Penn is subject to restrictive covenants during employment and for one year thereafter, including covenants not to solicit clients of the Company, hire or solicit employees or exclusive consultants of the Company, and render services for any client of the type rendered by the Company, subject to specified exceptions. Mr. Penn is also subject to a perpetual covenant not to disclose confidential information.

Executive Compensation

This section contains information, both narrative and tabular, regarding the compensation for fiscal 2018, 2017, and 2016 for (1) our principal executive officer in 2018; (2) our principal financial officer in 2018; and (3) our three other most highly compensated executive officers who were serving as executive officers as of the end of 2018 (collectively, the “ NEOs “ or the “ named executive officers “). Ms. Nerlich was not a NEO in 2016 or 2017. Therefore, in accordance with the SEC’s disclosure rules, information regarding compensation for the years that this individual was not a NEO is not included in the table below. In addition, Mark Penn was not appointed as the Company’s CEO until March 18, 2019. Therefore, in accordance with the SEC’s disclosure rules, information regarding compensation for Mr. Penn is not included in the table below.

SUMMARY COMPENSATION TABLE

(1)

As disclosed in the CD&A, the Company’s practice is to require senior executives to sign Incentive/​Retention Agreements in connection with each annual bonus payment, which agreement provide for a pro rata repayment of each bonus paid if he/she resigns or is terminated for cause within two years of the end of the performing year.

​

(2)

Reflects the grant date fair value of the equity awards we granted to our NEOs as determined in accordance with FASB Topic 718. For a discussion of the assumptions relating to these valuations, please see “Footnote 2 — Significant Accounting Policies” set forth in our annual report on Form 10-K for the year ended December 31, 2018. On February 28, 2018, the Company issued 2018 LTIP Equity Incentive Awards to each of the NEOs in the following target amounts: Scott Kauffman — 128,342 shares of restricted stock with a market value of  $1,007,485 on February 28, 2018; David Doft — 53,476 shares of restricted stock with a market value of  $419,787 on February 28, 2018; Mitchell Gendel — 53,476 shares of restricted stock with a market value of  $419,787 on February 28, 2018; Stephanie Nerlich — 26,738 shares of restricted stock with a market value of  $209,893 on February 28, 2018; and David Ross — 26,738 shares of restricted stock with a market value of $209,893 on February 28, 2018. Each of the foregoing restricted stock grants will vest on March 1, 2021, based on the Company’s Actual Cumulative EBITDA for the period commencing on January 1, 2018 and ending on December 31, 2020. See “Compensation Discussion and Analysis — Elements of our Compensation Program for our Named Executive Officers — 2018 LTIP Equity Incentive Awards.” Under FASB ASC Topic 718, these restricted stock awards do not yet have an established grant date fair value because the financial performance target is not yet established and are therefore not reflected in the table above. On January 19, 2018, the Committee established the Cumulative

As the date that the financial performance target was established for those awards, such date was the grant date for those awards. The values set forth in the table above for 2018, therefore, reflect the grant date fair value as determined in accordance with FASB Topic 718 of the 2016 LTIP Equity Incentive Awards. See “Compensation Discussion and Analysis — Elements of our Compensation Program for our Named Executive Officers — Forfeiture of 2016 LTIP Equity Incentive Awards.” The 2016 LTIP Equity Incentive Awards vest based on EBITDA. The grant date fair value was computed in accordance with FASB Topic 718 based upon the probable outcome of the performance conditions as of the grant date. Assuming the highest level of performance achievement as of the grant date, the aggregate grant date fair value of the performance awards would have been: Mr. Kauffman - $1,302,484; Mr. Doft - $366,000; Mr. Gendel - $366,000; and Mr. Ross - $274,500. However, all of the 2016 LTIP Equity Incentive Awards were forfeited in March 2019 due to failure to achieve the performance targets.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

We have entered into employment agreements with each of our named executive officers. Under these agreements, we are required to pay severance benefits in connection with specified terminations of employment, including specified terminations in connection with a change in control of the Company. The employment agreements for each NEO and other executives require a “double trigger” for any change in control severance payments. In addition, some of our equity incentive plans provide for the accelerated payment or vesting of awards in connection with specified terminations of employment or a change in control of the Company. The following is a description of the severance, termination and change in control benefits payable to each of our named executive officers pursuant to their respective employment agreements and our equity incentive plans.

Definitions of terms such as “change in control” or “for good reason” vary between agreements, so when a definition is particular to an agreement, it is described for that agreement. For all named executive officers, a “change of control” means the closing of a transaction which results in (1) any person(s) or company(ies) acting jointly or in concert owning equity of the Company representing greater than 50% of the voting power of the Company’s outstanding securities, or (2) the Company selling all or substantially all of its assets (in each instance other than any transfer by the Company or any of its affiliates of their respective interest in the Company to another wholly-owned subsidiary of another MDC Group company).

Scott L. Kauffman

On September 12, 2018, the Company entered into a Succession Agreement with Scott L. Kauffman, the Company’s former Chairman and Chief Executive Officer. Pursuant to the Succession Agreement, Mr. Kauffman resigned from his position as Chief Executive Officer of the Company on December 31, 2018 (the “Succession Date”). In accordance with the terms of the Succession Agreement, Mr. Kauffman was entitled to receive, subject to his execution and non-revocation of a customary release of claims, a cash separation payment equal to $3,600,000, payable in a single lump sum, subject to execution of a release of claims. Mr. Kauffman signed the applicable release and the Company paid him the separation payment on March 1, 2019. In addition, Mr. Kauffman’s outstanding long-term incentive awards will remain subject to the applicable performance-based vesting requirements under the respective award agreements, and will be pro-rated to reflect service through the Succession Date.

David Doft

Pursuant to his employment agreement, if MDC terminates Mr. Doft’s employment without cause, Mr. Doft terminates his employment for good reason, or the company gives a notice of non-renewal of the agreement, then MDC is required to pay Mr. Doft a severance payment within 10 days of the date of termination of one (1) times Mr. Doft’s total remuneration, plus an amount equal to two (2) month’s base salary for each calendar year in which he was employed by the Company, up to a maximum of six (6) months. Total remuneration means the sum of his current base salary, his perquisite allowance, plus the highest annual discretionary cash bonus he earned in the three years ending December 31 of the year immediately preceding the date of termination. If Mr. Doft’s employment had terminated under these circumstances on December 31, 2018, the aggregate cash payment due to him under the agreement would have been $1,655,000. Furthermore, Mr. Doft will also be allowed to continue participating for one year after termination on the same basis as before he was terminated in all benefit plans and, to the extent permitted under law, also in all retirement plans, provided however, that if Mr. Doft becomes entitled to receive coverage and benefits in the same type of plan from another employer, he will no longer be able to participate in these benefit and retirement plans. We will be obligated to pay him the economic equivalent of the benefits in these plans if Mr. Doft is unable to participate in the plans. The aggregate amount of this benefit would have been approximately $21,408 if Mr. Doft’s employment had terminated as of December 31, 2018. As of December 31, 2018, Mr. Doft had 111,159 unvested restricted stock grants that would vest on termination of his employment agreement, with a fair value equal to $290,124. In the event of termination of Mr. Doft’s employment agreement following a change of control as of December 31, 2018, a total of  (i) 173,476 unvested restricted stock grants would fully vest, with a fair value equal to $452,772, plus (ii) 50,000 SARs would fully vest, with a fair value equal to $130,500.

39

If Mr. Doft’s employment is terminated without cause by the company within one year following the closing of a change in control, by Mr. Doft for good reason, or by the company giving a notice of non-renewal of the agreement, then Mr. Doft will be entitled to a payment of 2.0 times his total remuneration. He will also be eligible to receive a pro rata portion of his annual discretionary cash bonus for the year in which his employment terminates. If there had been a change in control of MDC Partners on December 31, 2018 and Mr. Doft’s employment terminated in connection with that change in control, the aggregate cash severance payment MDC would have paid him under the contract would be $2,660,000. Furthermore, Mr. Doft will also be allowed to continue participating for one year after termination on the same basis as before he was terminated in all benefit plans. We will be obligated to pay him the economic equivalent of the benefits in these plans if Mr. Doft is unable to participate in the plans. The aggregate amount of this benefit would have been approximately $21,408 if Mr. Doft’s employment had terminated as of December 31, 2018.

Mitchell Gendel

Pursuant to his employment agreement, if MDC terminates Mr. Gendel’s employment without cause, Mr. Gendel terminates his employment for good reason, or the Company gives a notice of non-renewal of the agreement, then MDC is required to pay Mr. Gendel a severance payment within 10 days of the date of termination of one (1) times Mr. Gendel’s total remuneration, plus an amount equal to six (6) month’s base salary. Total remuneration means the sum of his current base salary, his perquisite allowance, plus the highest annual discretionary cash bonus he earned in the three years ending December 31 of the year immediately preceding the date of termination. If Mr. Gendel’s employment had terminated under these circumstances on December 31, 2018, the aggregate cash payment due to him under the agreement would have been $1,550,000. Furthermore, Mr. Gendel will also be allowed to continue participating for one year after termination on the same basis as before he was terminated in all benefit plans and, to the extent permitted under law, also in all retirement plans, provided, however, that if Mr. Gendel becomes entitled to receive coverage and benefits in the same type of plan from another employer, he will no longer be able to participate in these benefit and retirement plans. We will be obligated to pay him the economic equivalent of the benefits in these plans if Mr. Gendel is unable to participate in the plans. The aggregate amount of this benefit would have been approximately $23,184 if Mr. Gendel’s employment had terminated as of December 31, 2018. As of December 31, 2018, Mr. Gendel had 111,159 unvested restricted stock grants that would vest on termination of his employment agreement, with a fair value equal to $290,124. In the event of termination of Mr. Gendel’s employment agreement following a change of control as of December 31, 2018, a total of  (i) 173,476 unvested restricted stock grants would fully vest, with a fair value equal to $452,772, plus (ii) 50,000 SARs would fully vest, with a fair value equal to $130,500.

If Mr. Gendel’s employment is terminated within one year following the closing of a change in control by the company without cause, by Mr. Gendel for good reason, or by the company giving a notice of non-renewal of the agreement, then Mr. Gendel will be entitled to a payment of two (2) times his total remuneration. He will also be eligible to receive a pro-rata portion of his annual discretionary cash bonus for the year in which his employment terminates. If there had been a change in control of MDC Partners on December 31, 2018 and Mr. Gendel’s employment terminated in connection with that change in control, the aggregate cash severance payment MDC would have paid him under the contract would be $2,450,000. Furthermore, Mr. Gendel will also be allowed to continue participating for one year after termination on the same basis as before he was terminated in all benefit plans. We will be obligated to pay him the economic equivalent of the benefits in these plans if Mr. Gendel is unable to participate in the plans. The aggregate amount of this benefit would have been approximately $23,184 if Mr. Gendel’s employment had terminated as of December 31, 2018.

Stephanie Nerlich

Pursuant to her employment agreement, if MDC terminates Ms. Nerlich’s employment without cause, then MDC is required to pay Ms. Nerlich a severance payment over the applicable twelve (12) month severance period, equal to one (1) times Ms. Nerlich’s total remuneration. Total remuneration means the sum of her current base salary plus the highest annual discretionary cash bonus she earned in the three years ending December 31 of the year immediately preceding the date of termination. If Ms. Nerlich’s employment had terminated under these circumstances on December 31, 2018, the aggregate cash payment

40

due to her under the agreement would have been $848,500. As of December 31, 2018, Ms. Nerlich had 45,579 unvested restricted stock grants that would vest on termination of her employment agreement, with a fair value equal to $118,962. In the event of termination of Ms. Nerlich’s employment agreement following a change of control as of December 31, 2018, a total of  (i) 76,738 unvested restricted stock grants would fully vest, with a fair value equal to $200,286, plus (ii) 25,000 SARs would fully vest, with a fair value equal to $62,250.

If Ms. Nerlich’s employment is terminated following the closing of a change in control by the company without cause, then Ms. Nerlich will be entitled to a severance payment as calculated above.

David Ross

Pursuant to his employment agreement, if MDC terminates Mr. Ross’s employment without cause, or Mr. Ross terminates his employment for good reason, then MDC is required to pay Mr. Ross a severance payment within 10 days of the date of termination of one (1) times Mr. Ross’s total remuneration. Total remuneration means the sum of his then-current base salary plus the highest annual discretionary cash bonus he earned in the three years ending December 31 of the year immediately preceding the date of termination. If Mr. Ross’s employment had terminated under these circumstances on December 31, 2018, the aggregate cash payment due to him under the agreement would have been $1,000,000. Furthermore, Mr. Ross will also be allowed to continue participating for one year after termination on the same basis as before he was terminated in all benefit plans and, to the extent permitted under law, also in all retirement plans, provided, however, that if Mr. Ross becomes entitled to receive coverage and benefits in the same type of plan from another employer, he will no longer be able to participate in these benefit and retirement plans. We will be obligated to pay him the economic equivalent of the benefits in these plans if Mr. Ross is unable to participate in the plans. The aggregate amount of this benefit would have been approximately $21,408 if Mr. Ross’s employment had terminated as of December 31, 2018. As of December 31, 2018, Mr. Ross had 85,579 unvested restricted stock grants that would vest on termination of his employment agreement, with a fair value equal to $223,362. In the event of termination of Mr. Ross’s employment agreement following a change of control as of December 31, 2018, a total of  (i) 126,738 unvested restricted stock grants would fully vest, with a fair value equal to $330,786, plus (ii) 43,000 SARs would fully vest, with a fair value equal to $112,230.

If Mr. Ross’s employment is terminated within one year following the closing of a change in control by the company without cause, or by Mr. Ross for good reason, then Mr. Ross will be entitled to a payment of two (2) times his total remuneration. He will also be eligible to receive a pro-rata portion of his annual discretionary cash bonus for the year in which his employment terminates. If there had been a change in control of MDC Partners on December 31, 2018 and Mr. Ross’s employment terminated in connection with that change in control, the aggregate cash severance payment MDC would have paid him under the contract would be $2,000,000. Furthermore, Mr. Ross will also be allowed to continue participating for one year after termination on the same basis as before he was terminated in all benefit plans. We will be obligated to pay him the economic equivalent of the benefits in these plans if Mr. Ross is unable to participate in the plans. The aggregate amount of this benefit would have been approximately $21,408 if Mr. Ross’s employment had terminated as of December 31, 2018.

CEO Pay Ratio Disclosure

As required by Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K (“Item 402(u )”), the Company is providing the following reasonable estimate of the ratio of the median of the annual base salary compensation of all of our employees (except Scott L. Kauffman, our former Chairman and Chief Executive Officer (“CEO”)), to the annual total compensation of Mr. Kauffman, calculated in a manner consistent with Item 402(u). For 2018, our last completed fiscal year:

•

The median of the annual base salary compensation of all of our employees, excluding our CEO, was $80,300.

​

•

The annual total compensation of our CEO was $2,510,520, as disclosed in the Summary Compensation Total above.

​

41

Based on this information, the ratio of the annual total compensation of our CEO to the median of the annual base salary compensation of all of our employees except our CEO was approximately 31:1. The ratio of the annual base salary compensation of our CEO to the median of the annual base salary compensation of all of our employees except our CEO was approximately 15:1.

We determined that, as of December 31, 2018, our employee population consisted of approximately 6,100 individuals.

To identify our “median employee” from this employee population, we obtained from our internal compensation system base salary amounts for 2018 with respect to each employee in the employee population at the Company and its affiliates. We believe this consistently applied compensation measure reasonably reflects annual compensation across our employee base. Base salary amounts for employees located outside the United States and compensated in currencies other than U.S. dollars were converted to U.S. dollars based on the foreign exchange rates as of December 31, 2018. We annualized the base salary amounts for any permanent employees in the employee population who were employed by us for less than the full fiscal year. We then ranked the resulting base salaries for all the employees in the employee population other than our CEO to determine our median employee.

Compensation Committee Interlocks and Insider Participation

Mr. Larry Kramer (Chairman), Mr. Clare Copeland, Ms. Desiree Rogers and Mr. Irwin Simon served on the Human Resources & Compensation Committee of the Board of Directors during 2018. None of the persons who served on the Human Resources & Compensation Committee at the time of such service are, or have been, an employee or officer of the Company or had any relationship requiring disclosure under Item 404 of Regulation S-K. In addition, none of the Company’s executive officers serves, or has served during the last completed fiscal year, as a member of the board of directors or compensation committee of any other entity that has or has had one or more of its executive officers serving as a member of the Company’s Board of Directors.

Review and Approval of Related Party Transactions

The Board has adopted a written Related Party Transactions Policy to assist it in reviewing, approving and ratifying related party transactions. The Related Party Transactions Policy provides that all related party transactions covered by the policy must be approved in advance by the Audit Committee, except that any ordinary course transaction in which an operating subsidiary of the Company derives revenue from a related party may be approved on an annual basis by the Audit Committee. To facilitate compliance with this policy, Directors and executive officers of the Company must notify the Company’s General Counsel and CFO as soon as reasonably practicable about any potential related party transaction. If the Company’s General Counsel and CFO determine that the transaction constitutes a related party transaction, the transaction will be referred to the Audit Committee for its consideration. The Audit Committee will be provided with full details of the proposed related party transaction, including: the terms and conditions of the proposed transaction; the business purpose of the transaction; and the benefits to the Company and to the relevant related party.

43

In reviewing related party transactions, the Audit Committee will consider all relevant facts and circumstances, including, among others:

•

The benefits of the transaction to the Company;

​

•

The terms of the transaction and whether they are fair (arm’s-length) and in the ordinary course of the Company’s business; and

​

•

The size and expected term of the transaction.

​

Generally, the Related Party Transactions Policy applies to any transaction that would be required by the SEC to be disclosed in which the Company was or is proposed to be, a participant and in which a “Related Party” had, has or will have a direct or indirect material interest. The policy also applies to any amendment or modification to an existing Related Party Transaction, regardless of whether such transaction has previously been approved.

Related Party Transaction

The Company engaged in the following related party transaction in 2018, which was reviewed and approved by the Audit Committee in accordance with the Related Party Transactions Policy described above:

REPORT OF THE AUDIT COMMITTEE OF THE BOARD

The Audit Committee is responsible for assisting the Board in serving as an oversight to MDC Partners’ accounting, auditing, financial reporting, internal control and legal compliance functions. The Audit Committee has implemented procedures to ensure that during the course of each fiscal year, it devotes the attention that it deems necessary or appropriate to each of the matters assigned to it under its charter including, whenever appropriate, meeting in executive sessions with MDC Partners’ independent auditors without the presence of MDC Partners’ management.

Management is responsible for the financial reporting process, including the system of internal controls, for the preparation of consolidated financial statements in accordance with U.S. generally accepted accounting principles (“GAAP”) and for the report on the Company’s internal control over financial reporting. The Company’s independent auditors are responsible for auditing those consolidated financial statements and expressing an opinion as to their conformity with GAAP and for opining on the effectiveness of the Company’s internal control over financial reporting. The Audit Committee’s responsibility is to oversee and review the financial reporting process and to review and discuss the status and completed copy of management’s report on the Company’s internal control over financial reporting.

The Audit Committee reviewed and discussed with management and BDO USA, LLP, the Company’s independent registered accountants, management’s assessment of the Company’s internal controls over financial reporting in accordance with Section 404 of the Sarbanes-Oxley Act of 2002, as presented in the Company’s Annual Report on Form 10-K for the year ended December 31, 2018.

In overseeing the preparation of MDC Partners’ financial statements, the Audit Committee met with both management and MDC Partners’ outside auditors to review and discuss all financial statements prior to their issuance and to discuss significant accounting issues. Management advised the Audit Committee that all financial statements were prepared in accordance with GAAP, and the Audit Committee discussed the statements with both management and the outside auditors.

With respect to MDC Partners’ outside auditors, the Audit Committee, among other things, discussed with BDO USA, LLP matters relating to its independence, and received from BDO USA, LLP written disclosures and a letter from BDO USA, LLP as required by the applicable requirements of the Public Company Accounting Oversight Board. The Audit Committee also discussed with the independent registered public accounting firm the matters required to be discussed by PCAOB Standards Section No. 1301, “Communications with Audit Committee”, as amended, which includes, among other items, matters related to the conduct of the annual audit of MDC Partners’ financial statements.

On the basis of their reviews and discussions, the Audit Committee recommended to the Board that the Board approve (and the Board has approved) the inclusion of MDC Partners’ audited financial statements in MDC Partners’ Annual Report on Form 10-K for the fiscal year ended December 31, 2018, for filing with the Securities and Exchange Commission and the Canadian Securities Administrators.

Effective April 2006, the Company engaged BDO USA, LLP as its independent registered public accounting firm. The decision to engage BDO USA, LLP was made by the Audit Committee of the Board of Directors and the Board of Directors of the Company. The Committee and the Board have also approved, and submitted for shareholder approval, the selection of BDO USA, LLP as MDC Partners’ independent auditors for the fiscal year ending December 31, 2019.

The Audit Committee’s current charter is appended to this Circular as Exhibit A.

ITEM 2 — APPOINTMENT OF AUDITORS
AND AUTHORIZING THE AUDIT COMMITTEE TO DETERMINE ITS REMUNERATION

Subject to the action of the shareholders, upon recommendation of the Audit Committee, the Board has recommended to the shareholders the appointment of BDO USA, LLP, independent registered public accountants, to audit and report on the consolidated financial statements of MDC Partners for the fiscal year ending December 31, 2019 and to perform such other services as may be required of them. BDO USA, LLP has served as independent public accountants for MDC Partners since April 2006. The Board has directed that management submit the appointment of the auditors for approval by the shareholders at the Meeting. Representatives of BDO USA, LLP are expected to be present at the meeting, will have the opportunity to make a statement if they desire to do so and will be available to respond to appropriate shareholder questions.

Unless otherwise instructed, the persons named in the accompanying proxy (provided the same is duly executed in their favor and is duly deposited) intend to vote FOR the appointment of BDO USA, LLP, independent registered public accountants, as auditors of MDC Partners, until the close of the next annual meeting of shareholders of MDC Partners, at a remuneration to be fixed by the directors of MDC Partners.

In addition to retaining BDO USA, LLP to audit MDC Partners’ consolidated financial statements for 2017 and 2018, the Company retained BDO USA, LLP to provide advisory, auditing and consulting services in 2017 and 2018. These services included audit services, audit-related services, tax services and other services. The following tables set forth the aggregate fees billed to MDC Partners by BDO USA, LLP for professional services in fiscal years 2017 and 2018:

BDO USA, LLP

(1)

Fees primarily for the annual financial statement audit, including internal control assessment related fees, quarterly financial statement reviews and regulatory comment letters.

​

(2)

Fees for services rendered for foreign tax services.

​

All fees listed above have been pre-approved by the Audit Committee. The Audit Committee has, however, delegated to the Chairman of the Audit Committee the authority to pre-approve permitted non-audit services (as such services are defined by the Sarbanes-Oxley Act of 2002) provided that (i) the aggregate estimated amount of such fees will not exceed $25,000 and (ii) the Chairman of the Audit Committee reports any pre-approval so granted at the next scheduled meeting of the Audit Committee.

The Audit Committee Charter provides for the Audit Committee to establish the auditors’ fees. Such fees have been based upon the complexity of the matters in question and the time incurred by the auditors.

ITEM 3 — ADVISORY VOTE TO APPROVE EXECUTIVE COMPENSATION

The guiding principles of the Company’s compensation policies and decisions include aligning each executive’s compensation with our business strategy and the interests of our shareholders and providing incentives needed to attract, motivate and retain key executives who are important to our long-term success. Consistent with this philosophy, a significant portion of the total incentive compensation for each of our executives is directly related to the Company’s earnings and to other performance factors that measure our progress against the goals of our strategic and operating plans, as well as performance against our peers.

Shareholders are urged to read the Compensation Discussion and Analysis section of this Proxy Statement, as well as the Summary Compensation Table and other related compensation tables and narrative, which discuss how our compensation design and practices reflect our compensation philosophy. The Compensation Committee and the Board of Directors believe that our compensation design and practices are effective in implementing our guiding principles.

In accordance with Section 14A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and as a matter of good corporate governance, we are asking shareholders to approve the following advisory resolution at the 2019 Annual Meeting of Shareholders:

“RESOLVED, that the compensation paid to the Company’s named executive officers, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Discussion and Analysis, compensation tables and narrative discussion contained in this Proxy Statement, is hereby APPROVED.”

This advisory resolution, commonly referred to as a “say-on-pay” resolution, is non-binding on the Board of Directors. Although non-binding, the Board of Directors and the Compensation Committee value the opinions of our shareholders and will review and consider the voting results when making future decisions regarding our executive compensation program. The next advisory “say-on-pay” resolution will occur at the 2020 Annual Meeting of Shareholders.

YOUR BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR”
THE ADVISORY RESOLUTION TO APPROVE EXECUTIVE COMPENSATION.

The following directors of MDC Partners also serve as directors (or senior executive officers) of companies that are reporting issuers (or the equivalent) in Canada or the U.S.:

Mark J. Penn:   currently serves as the Chief Executive Officer. He is also the President and Managing Partner of The Stagwell Group.

Charlene Barshefsky:   currently serves as Senior International Partner at WilmerHale. She is also a director of the American Express Company and the Estee Lauder Companies, is a trustee of the Howard Hughes Media Institute and is a member of the Council on Foreign Relations.

Daniel S. Goldberg:   currently serves as President and Chief Executive Officer of Telesat.

Bradley J. Gross:   currently serves as a Managing Director at Goldman Sachs & Co. He is also a director of Americold Realty Trust, Neovia Logistics Holdings, Proquest Holdings and Open Road Parent.

Annie Marie O’Donovan:   currently serves as a director of Indigo Books & Music, Inc., Aviva Canada, Cadillac Fairview and Investco.

Kristen M. O’Hara:   currently serves as a trustee of the Signature Theatre Company.

Desirée Rogers:   currently serves as Chairman of Choose Chicago and of One Brown Girl. She is also a director of World Business Chicago, Cradles to Crayons, The Economic Club of Chicago, Conquer Cancer Foundation, Donors Choose and Inspired Entertainment.

Irwin D. Simon:   currently serves as Chairman and Chief Executive Officer of Aphria Inc. He is also a director of Barnes & Noble and a trustee at Tulane University and Poly Prep Country Day School.

All independent directors frequently meet at the beginning or end of each regularly scheduled quarterly Board or Committee meeting without non-independent directors and management present. The Board has access to information independent of management through MDC Partners’ auditor who reports to the Audit Committee. The specific responsibilities of the Board include reviewing and approving all major strategic decisions, including any change in the strategic direction of MDC Partners and acquisitions and/or divestitures and other matters (such as guarantees) in excess of  $5 million; reviewing and approving annual budgets, including capital expenditure plans; reviewing and approving operating results for each quarter and year to date. As part of its ongoing activities, the Board regularly receives and comments upon reports of management as to the performance of MDC Partners’ business and management’s expectations. The Board is therefore of the view that the appropriate structures and procedures are in place to ensure that it can function independent of management.

Effective as of July 20, 2015, the Board appointed Mr. Irwin Simon as the Presiding Director of the Board. Mr. Simon is independent.

Board Mandate

The Board of Directors recently adopted a set of Corporate Governance Guidelines as a framework within which the Board and its Committees will conduct its business. A copy of the Guidelines is available free of charge at MDC Partners’ website at http://www.mdc-partners.com/investors/corporate-governance.

Position Descriptions

The Company’s bylaws and the Charters of each Board committee provide a detailed description of the roles and responsibilities of the Board (including the Chairman), management and each committee of the Board and their respective chairs.

The primary functions of the CEO are to lead the management of our businesses and affairs in accordance with the Company’s strategic plan and operating and capital budgets, as approved by the Board.

The Board has developed a written position description and mandate, which sets forth the CEO’s key responsibilities. These responsibilities include the following: (a) develop and recommend to the Board a long-term strategy and vision for the Company that leads to creation of shareholder value; (b) develop and recommend to the Board annual business plans and budgets that support the Company’s long-term strategy; (c) consistently strive to achieve the Company’s financial and operating goals and objectives; and (d) develop the corporate and partner management teams and succession plans.

The Human Resources & Compensation Committee (described below) is responsible for establishing, monitoring and evaluating objectives and standards of performance for the Chief Executive Officer and other executive officers on an annual basis. Salary, bonus, loans or other payments for the benefit of the Chief Executive Officer must be reviewed and approved by the Human Resources & Compensation Committee. Related party expenses for services rendered and in the nature of expense reimbursement must also be approved by the Human Resources & Compensation Committee.

Orientation and Continuing Education

New directors to MDC Partners have generally been executives with extensive business experience and directorship responsibilities on the boards of other public and private institutions. Orientation for these individuals is provided through a review of past Board materials and other private and public documents concerning MDC Partners. In addition, Board members are encouraged to attend (at the cost and expense of the Company) continuing education programs identified by the Nominating and Corporate Governance Committee each year to ensure that they maintain the skills necessary for them to meet their obligations as directors.

Ethical Business Conduct

The Company has adopted a Code of Conduct, which applies to all directors, officers (including the Company’s Chief Executive Officer and Chief Financial Officer) and employees of the Company and its subsidiaries. The Code of Conduct was adopted in order to help directors, officers and employees resolve ethical issues. The Code of Conduct covers topics including, but not limited to, conflicts of interest, confidentiality of information and compliance with laws. The Company’s policy is to not permit any waiver of the Code of Conduct for any director or executive officer, except in extremely limited circumstances. The Board, through the Audit Committee, monitors and assesses and claims alleged under the Code of Conduct. Any waiver of this Code of Conduct for directors or officers of the Company must be approved by the Company’s Board of Directors. Amendments to and waivers of the Code of Conduct will be publicly disclosed as required by applicable laws, rules and regulations. The Code of Conduct is available free of charge on the Company’s website at http://www.mdc-partners.com, or by writing to MDC Partners Inc., 745 Fifth Avenue, 19th Floor, New York, NY 10151, Attention: Investor Relations.

Nomination of Directors

The Nominating and Corporate Governance Committee is composed of three (3) members, all of whom are considered to be independent. The Nominating and Corporate Governance Committee is responsible for reviewing and making recommendations to the full Board with respect to developments in the area of corporate governance and the practices of the Board. The Nominating and Corporate Governance Committee

B-2

is also responsible for evaluating the performance of the Board as a whole and for reporting to the Board with respect to appropriate candidates for nominations to the Board. The current members of the Nominating and Corporate Governance Committee are Irwin Simon (Chairman), Larry Kramer and Anne Marie O’Donovan. The Nominating and Corporate Governance Committee’s current charter is available at http://www.mdc-partners.com/investors/corporate-governance. The Company will disclose any amendments to, or waivers of, the charter on its website at www.mdc-partners.com in accordance with applicable law and the requirements of the Nasdaq corporate governance standards.

The Nominating and Corporate Governance Committee identifies, selects and recommends to the Board individuals qualified to serve both on the Board and on committees, including persons suggested by shareholders and others. In identifying candidates for nominations to the Board, the Nominating and Corporate Governance Committee seeks to maintain at all times a Board with a diverse range of experience, talent, expertise and background appropriate for the business of the Company. The Nominating and Corporate Governance Committee does not require any specific minimum qualifications or specific qualities or skills, but reviews each person’s qualifications on the whole, including a candidate’s particular experience, skills, expertise, diversity, personal and professional integrity, character, business judgment, time availability in light of other commitments, dedication, conflicts of interest and such other relevant factors that the Nominating and Corporate Governance Committee considers appropriate in the context of the needs of the Board. Following that review, the Nominating and Corporate Governance Committee then selects nominees and recommends them to the Board for election by the shareholders or appointment by the Board, as the case may be. The Nominating and Corporate Governance Committee also reviews the suitability of each Board member for continued service as a director when that member’s term expires or that member experiences a significant change in status (for example, a change in employment). The Nominating and Corporate Governance Committee has not implemented any particular additional policies or procedures with respect to suggestions received from shareholders with respect to Board or committee nominees.

Pursuant to its charter, the Nominating and Corporate Governance Committee may conduct or authorize investigations or studies into matters with its scope of responsibilities and may retain, at the Company’s expense, such independent counsel or other consultants or advisers at it may deem necessary from time to time. The Nominating and Corporate Governance Committee has the sole authority to retain or terminate any search firm to be used to identify director candidates, including the sole authority to approve its fees and retention terms, with the Company bearing the cost of such fees.

Director Term Limits

The Board believes that the need to have experienced directors who are familiar with the business of the Company must be balanced with the need for fresh perspectives and a proactive approach. The Board has not adopted formal director term limits or other mechanisms of board renewal, in part, because the imposition of director term limits on a board implicitly discounts the value of experience and continuity among board members and runs the risk of excluding experienced and potentially valuable board members as a result of an arbitrary determination. In addition, imposing this restriction means the Board would lose the contributions of longer serving directors who have developed a deeper knowledge and understanding of the Company over time. The Board does not believe that long tenure impairs a director’s ability to act independently of management.

Policies Regarding the Representation of Women on the Board

The Company has not adopted a written policy relating to the identification and nomination of women directors to the Company’s board of directors but rather has an informal, unwritten policy, but the addition of at least one woman was a priority for 2018. The Company generally considers diversity of race, ethnicity, gender, age, cultural background and professional experience in evaluating candidates for board membership. As evidence of this approach, the Board nominated Ms. O’Donovan to join the Board in 2017, Ms. Rogers to join the Board in April 2018 and Ambassador Barshefsky to join the Board in April 2019. Ms. O’Hara was nominated for election to the Board in April 2019.

B-3

Consideration of the Representation of Women in the Director Identification and Selection Process

In identifying and nominating candidates for election or re-election to the board of directors, the Board considers the level of representation of women on the board, in addition to the competencies, skills and personal and other diverse qualities required for new directors in order to add value to the Company in light

of opportunities and risks facing the Company. Selection of female candidates to the board will be, in part, dependent upon the pool of female candidates with the necessary skills, knowledge and experience. The ultimate decision will be based on merit and contribution the chosen candidate will bring to the board.

Consideration of the Representation of Women in Executive Officer Appointments

In appointing executive officers to the management team, the Company considers the level of representation of women in executive officer positions, and also takes into account the following factors: the competencies, skills and personal and other diverse qualities required for new executive officers in order to add value to the Company in light of opportunities and risks facing the Company.

Issuer’s Targets Regarding the Representation of Women on the Board and in Executive Officer Positions

The Company has not adopted a target for women on the board of directors because the Company does not believe that any director nominee should be chosen nor excluded because of gender. In selecting a director nominee, such as recently appointed Ms. O’Donovan, Ms. Rogers and Ms. Barshefsky, the Nominating and Corporate Governance Committee focuses on skills, expertise and background that would complement the existing Board. Directors will be recruited based on their ability and potential for meaningful contributions.

Similarly, the Company has not adopted a target for women in executive officer positions because the Company does not believe that any candidate for an executive officer position should be chosen nor excluded because of gender. In selecting candidates, the Company considers the skills, expertise and background that would complement the existing management team. Executive officers will be recruited based on their ability and contributions.

Number of Women on the Board and in Executive Officer Positions

As of the date of this Proxy Statement and Management Information Circular, (i) there are three women on the Company’s Board of Directors, representing 30% of the directors and (ii) five (5) of the Company’s executive officers are women, representing approximately 38% of the Company’s executive officers.

Compensation

The Human Resources & Compensation Committee is composed of three members, all of whom are considered to be independent. The Human Resources & Compensation Committee makes recommendations to the Board on, among other things, the compensation of senior executives. The Human Resources & Compensation Committee discusses personnel and human resources matters including recruitment and development, management succession and benefits plans and grants awards under the 2011 Stock Incentive Plan, the 2016 Stock Incentive Plan and the SARs Plan. Salary, bonus or other payments for the benefit of senior management are reviewed and approved by the Human Resources & Compensation Committee. The Human Resources & Compensation Committee reviews the compensation of members of the Board on an annual basis and makes recommendations to the Board. The Board considers their remuneration appropriate given the time commitment, risk and responsibilities associated with the position. The current members of the Human Resources & Compensation Committee are Clare Copeland (Chairman), Larry Kramer, Irwin Simon and Desiree Rogers. The Human Resources & Compensation Committee’s current charter is available at http://www.mdc-partners.com/investors/​corporate-governance. The Company will disclose any amendments to, or waivers of, the charter on its website at www.mdc-partners.com in accordance with applicable law and the requirements of the Nasdaq corporate governance standards.

B-4

Other Board Committees

The Board conducts its business through meetings of the Board and three standing committees: the Audit Committee, the Human Resources & Compensation Committee and the Nominating and Corporate Governance Committee. Copies of the charters of these committees are available, free of charge at MDC Partners’ website located at http://www.mdc-partners.com/investors/corporate-governance.

In addition, from time to time, special committees may be established under the direction of the Board when necessary to address specific issues.

Assessments

The Nominating and Corporate Governance Committee is responsible for developing and recommending standards of performance of the Board, its committees and the individual directors through administration of an annual questionnaire. It is the responsibility of the Nominating and Corporate Governance Committee to assess the effectiveness of the Board as a whole and the committees of the Board. Participation of directors is expected at all Board and committee meetings. Directors are asked to notify MDC Partners if they are unable to attend, and attendance at meetings is duly recorded.
